There is one aspect of this proposal we are going to change: The idea is to completely remove the
version identifier from the network identifier. So the definition of the `network identifier will be:
network identifier = H(nethash + community identifier)
The motivation behind this change is the following:
We believe that bumping the version in the network identifier for every hard fork is an excessively strict rule. In the future, this will imply to upgrade not only the running nodes, but every other third party tool using the API or Lisk Elements. And this would also apply for sidechains, which would make the process unnecessarily arduous for the developer.
Bear in mind that this change does not lower the security against transaction replay attacks as long as a proper validation process is defined when a certain transaction type is updated/created.
I’ll create a pull request to change this detail very soon.
